What's all the fuss about the new sheet masks? Besides being virtually mess-free, dummyproof, and travel-friendly, these single-use masks take skin transformation to a whole new level. "The fabric sheets are soaked in serum—a light liquid made of very small molecules—so ingredients penetrate faster and more deeply than a standard cream or gel mask," says New York City dermatologist Joshua Zeichner, MD.
